The minimum input voltage required for the LM1851M to operate is 4.5V, but it's recommended to use a minimum of 5V to ensure proper operation and stability.
To ensure the output voltage is accurate and stable, it's recommended to decouple the input and output pins with capacitors (e.g., 10uF and 100nF respectively), and to use a low-ESR capacitor (e.g., 10uF) on the output pin to filter out noise and ripple.
The maximum output current that the LM1851M can supply is 10mA, but it's recommended to limit the output current to 5mA or less to ensure stability and accuracy.
During power-up, the LM1851M's output voltage may take some time to settle to its final value, typically around 10ms. During power-down, the output voltage will decay rapidly to zero. It's recommended to use a soft-start circuit or a voltage supervisor to ensure a clean power-up and power-down sequence.
No, the LM1851M is a voltage reference, not a voltage regulator. It's designed to provide a stable voltage reference, but it's not intended to regulate the output voltage under varying input conditions or load currents.
